Apple Releases iOS 27.2 and iPadOS 27.2, Patching 163 Vulnerabilities Including Exploited Flaws in Older Versions

Apple has released security updates for its mobile operating systems, delivering fixes for a total of 163 vulnerabilities across multiple versions of iOS and iPadOS.

The company published iOS 27.2 and iPadOS 27.2 on October 26, 2026. These updates resolve issues in WebKit, the kernel, and image handling functions. Among the fixes is CVE-2026-113897, which could allow remote attackers to bypass the WebContent sandbox.

Apple also issued updates for older releases. iOS 26.7.2 and iPadOS 26.7.2 address 134 vulnerabilities, including CVE-2026-64759 in the ImageIO framework that could permit arbitrary code execution via crafted images.

Further back, iOS 18.7.11 and iPadOS 18.7.11 receive patches for three vulnerabilities, one of which (CVE-2026-86950) has already been exploited in the wild.

The updates are available for compatible iPhone and iPad models. Users are advised to install them promptly to mitigate the reported risks.

CISA Adds PHP2Shell Flaws CVE-2026-109618 and CVE-2026-109619 to KEV Catalog After Confirmed Exploitation

The U.S. Cybersecurity and Infrastructure Security Agency has confirmed active exploitation of two remotely exploitable vulnerabilities in PHP collectively known as PHP2Shell. CVE-2026-109618 stems from improper handling during memory exhaustion, while CVE-2026-109619 involves use-after-free issues in internal state management. Both flaws allow unauthenticated remote code execution and pose elevated risk to any PHP environment processing external requests such as web servers. PHP development teams released patches on October 21 for supported branches including PHP 8.5.12, 8.4.27, 8.3.36 and 8.2.35, along with source-level fixes for end-of-life versions 7.4, 8.0 and 8.1. CISA has set a three-day remediation deadline of October 29 for U.S. federal agencies and requires verification that systems have not been compromised.

Security Week 2644: Active Exploitation of PHP2Shell Vulnerabilities Confirmed

PHP developers released patches for two critical vulnerabilities collectively known as PHP2Shell on October 20, affecting PHP 8.2 through 8.5 as well as older branches. The flaws allow unauthenticated remote code execution on affected servers, which power approximately 70 percent of websites. Despite expectations of immediate exploitation, confirmed attacks with working exploits only began on October 25. CrowdStrike noted technical difficulties in weaponizing the issues in real-world environments. Only one-fifth of top Russian websites had applied the fixes by October 25. Additional incidents included compromised eMudhra certificates, a critical GitLab flaw, and a 16-year-old Broadcom router vulnerability.

Positive Technologies Offers Up to 500,000 Rubles for Bypassing PT Application Firewall

Positive Technologies has expanded its Standoff Bug Bounty program to include rewards for bypassing its web application firewalls. Researchers can earn between 150,000 and 500,000 rubles for demonstrating practical bypasses against PT Application Firewall PRO and PT Application Firewall Cloud. The program targets the core protective mechanisms, including traffic filtering, attack detection rules, and the management layer used by administrators. Submissions must include reproducible attack scenarios that show how malicious requests can pass through undetected, rather than relying on scanner reports or theoretical findings. Reward amounts vary by severity and confirmed business impact, with critical issues in the PRO version paying up to 500,000 rubles. The company plans to use validated findings to strengthen detection rules and improve overall product resilience.

Tailscale SSH Vulnerability Allows Root Access via Unix Socket Redirection

A researcher identified flaws in Tailscale that let an attacker with existing SSH access on one node escalate to root privileges and move laterally across the network. Erica Windisch of Cyberdione Labs demonstrated the issues in lab conditions against Tailscale 1.104.2 and Headscale 0.29.5. The core problem stems from privileged operations performed by the tailscaled process when handling Unix socket redirection, granting an ordinary SSH session access to root-only resources. The researcher used the technique to interact with Docker and run elevated commands, and showed that broad access policies allow automated lateral movement in under a second. Additional issues include denial-of-service conditions and bypasses of certain restrictions. Recommendations include reviewing SSH policies and disabling unnecessary socket redirection, noting that Headscale 0.29.5 lacks an independent way to turn the feature off.
